BAILER.

Application filed .Tune 25, 1927.

rlhis invention relates to bailers, and more particularly to bailers convertible for use in the supply of water to oil wells and the like.

The invention has for its objectthe provision Aof new and improved means to loch a bailer valve in its open position.

Another object of the invention is to provide a strong and durable valve locking member of elli-cient operation, and having means to hold the saine in an inoperative position.

A further object ofthe invention is the provision of an element adapted to be attached to any bailer of this type for cooperation with the valve locking member.

Various other objects will hereinafter appear.

In the accompanying drawino's, which are illustrative of the preferred embodiment of the invention; Fig. l is a sectional side ele vation of the lower end of the bailer with the valve tongue partly in section projecting therefrom. Fig. 2 is a side elevation of tie lower end of the bailer, taken at right angles to F l. Fig. 3 is a sectional side elevation of a modification, and discloses t` e lower end of a bailer provided with'a ring engaged by the dogs to hold the valve in open position; and Fig. l is a detail view of the ring.

Referring specifically to the drawings, the lower end of the bailer is indicated at l and has a valve seat 2 suitably secured therein. The valve S having a tongue 3, is shown in its open position in Fig. 3.

For reasons well-known to those skilled in the erw-for example, to prevent caving init frequently becomes necessary to pour water into the well. Iell bailers of the ordinary type have heretofore been used for this purpose, various devices beine' employed to prevent closure of the valves thereof and thus permit escape of the water into the Well. These devices, however, have been inefficient, and this invention provides strong, durable and eiiicient means to obviate the difficulties heretofore experienced in the use of the devices referred to.

The said means comprises a Vpair of disclike members or dogs 4l rotatably mounted upon pins 5 which extend through tongue 3". Each of pins 5 projects from both sides of tongue 3a; one end thereof rotatably carries one of dogs l which is held thereon by nut 6; the other end thereof extends into an arcuate slot In in the other of said dogs;

and the intermediate portion thereof is screw-threaded whereby it is secured to the tongue 3a.

From the foregoing, it will be understood that each of the dogs -l has an opening' to receive one end of one pin and an arcuate slot da to receive the opposite end of the other of said pins. The dogs may be recessed, as shown, for the reception of nut 6 adapted to be engaged by a spanner wrench. By the means described, the dogs will be rotatably supported in an operative position, and may be non-rotatably secure-d in an inoperative position.

The valve 2 has an internal annular groove 2aM into which dogs 4 are adapted to project.

The force of gravity normally holds the disc-shaped dogs 4 in the position illustrated in F 2, the said dogs being' eccentrically and rotatably nioi'lnted upon the ends of pins 5. The center of rotation and center of gravity not being coincident, the dogs rotate to the position of Fig. 2, and further rotation thereof is prevented by the engagement of pins 5 and the upper end walls of arcuate slots lla. To permit this rotation in order that the device may be used as a dump bailer, or to supply water to the well, the nuts 5 are not tightly screwed on. IVhen the device is so used, the downward movement of tongue 3a is arrested by Contact thereof with the bottom of the hole, the thereafter continued downward movement of boiler l effects a rotation of the dogs in one direction, and when the groove 2 has reached a vposition opposite the dogs, the dogs rotate in the opposite direction, enter said groove, and lock valve tongue 3, thus holding valve 3 in its open position. The empty bailer is then removed from the hole. When the device is to be used as an ordinary bailer for the removal of water from the hole, it is necessary only to si 1ing the dogs into an inoperative position, and tighten nuts 6. In this position, the Clogs will not extend beyond the sides of tongue 3 and will therefore not enter groove 2 to prevent the seating of the valve when the bailer is moved upwardly.

In the' form shown in Figs. l and 2, the dogs rest upon the shoulder provided by the lower wall of annular groove'Qa. It is to be understood, however, that any suitable element may be provided, either integral with or attachable to the bailer, to provide a shoulder to be engaged by the doge. Reforring to Figs. 3 and 4,' a bailer of the ordinary type is indicated at l. A ring divided diametrically into tivo sections 7, 7 may be Welded to the bottom thereof to provide an internal shoulder to be engaged by the doge el. The upper outer edge of the ring` may be beveled as at 7a to form a circumferential Welding groove. The attachment oi the ring;` to the baile-r, however, may be effected by bolts, or otherwise. v

The inventionis not limited to the specie embodiment shown, and various changes may be mane Without departure from the scope or" the following claims.

l claim:

l. The combination with a bailer having' a valve therein, of a pair of pins carried by said valve, a dog rotatablv mounted on one of said pins and having a slot into which the other of said pins extends to limit the rotation of said dog. i

2. rEhe combination with a bailer having a valve therein, ot a pair of pineI carried by @aid valve, a pair ot' doge, each of said doge being rotatably mounted on one of said pins, said dogs having slots, and each of said pins extending` into the slot of the dogmounted upon the other of Said pins.

3. A bailer, a valve carried thereby, and a valve-controlling dog rotatably mounted on said valve and adapte-d to engage said bailer to prevent the closure of Said valve.

l. A bailer, a valve carried thereby, and a valve-controlling dog rotatably mounted on said valve, and adapted to engage said bailer to prevent the closure of said valve, and means carried by said valve to hold said dog out of engagement with said bailer.

5. The combination with a bailer having a normally seated valve projecting from the bottom thereof and adapted to be vunseated by contact With the bottom of a hole when the bailer is lowered therein, of a valve-controlling` dogl rotatably mounted on said valve and adapted to engage said bailer to prevent the closure of said valve.

6. The combination With a bailer having a normally seated valve projecting from the bottom thereof and adapted to be nneeated by Contact With the bottom of a hole when the bailer is lowered therein, of a valve-controlling dog rotatably mounted on said valve and adapted to engage said bailer, to prevent the closure of said valve, andrmeane carried v by said valve o hold said dog out of eentact with Said bailer. Y

7. A valve dog comprising a dise-like body having linger, said body having a bearing opening on that side of its center of gravity adjacent said Vlinger.

8. A valve dogg,` comprising` a disc-like body having a. finger, said body having` a bearing opening; on that side of its center of gravity adjacent Said linger, and an arcuate slot.

9. The combination with a bailer and a reeiprocable valve carried thereby, of dog rotatably mounted on the side o1 said valve and engaging Said bailer to permit the opening` and prevent the closure ot said valve.

10. The Combination With a bailer and a reeipiocable valve carried thereby, of a dog rotatably mounted on the side of said valve and engaging said bailer to permit the opening` and prevent the closure of said valve, and means to releasably hold said dog out of engagement With said bailer to permit the closure of said valve.

In testimony whereof, I

- hereunto ai'lix my nature.
